I found a similar issue here.
solr facet search truncate words
When I use solr facet for manufacturer name of products, then although the actual manufacturer name is like "化学商品", but in solr navigation area it shows up as two options: "化学" and "商品", which means it is stemming. For English manufacturer name it is working fine.
I cannot use fieldType string. I am using text.
How do I avoid it for Japanese characters so that it shows only the full manufacturer name. I also tried using the Tokenizer class CJKTokenizerFactory, but it didn't work.
Any help is greatly appreciated!
You cannot use text for facets. If you wish to both search and facet on manufacturer name then extract this information twice, once as string and once as text and use these different representations in appropriate places.

I am looking for a way of querying for values in multiple fields. Basically i am building a simple search engine where user can type ie. "Java How to XML JSON" and it will search for these values in 3 different fields categories, tags, description.
I read on some blog I should query all fields q=*:* and then filter based on those fields for example fq=categories:java,xml,how,to,json description:java,xml,how,to,json tags:java,xml,how,to,json
This works :| But it seems incorrect to just copy paste values like this.
Is there a correct way of doing this? I have been researching this for some time but i havent found a solution.
Any help is appreciated,
Thank you
You can use defType=edismax to get the extended dismax handler. This is meant to handle user typed queries (i.e. what you'd type in). You can then use qf (query fields) to tell the edismax handler which fields you want to search (and an optional weight for each field):
q=Java How to XML JSON&defType=edismax&qf=categories^5 tags description
.. will search each part of the string "Java How to XML JSON" in all the fields, and any hits in the categories field will be weighted five times higher than hits in the other two fields.
I would like to sort solr documents based on searched term. For example the search term is "stringABC"
Then the order of the results should be
stringABC,
stringABCxxxx,
xxxxstringABCxxxx
The solr document will contain lot of fileds ex: title, description, path, article No, Product code etc..
And the default field will contain more than one field ex: title, description and path.
So the solr doc will only be returned when the search term satisfied any field from the default field.
Use three fields - one with the exact string, one with a EdgeNgramTokenizer and one with an NgramTokenizer. You can then use qf=field1^10 field2^5 field3 to score hits in these fields according to how you want to prioritize them between each other.
I'm following this tutorial on how to perform indexing on sample documents using Solr. The default collection is "gettingstarted" as shown. Now I'm trying to query it. There are 52 entries as shown:
However, when I replace the q argument with say electronics, it should return 14 results. However, I get nothing.
When I replace the query string q with cat:electronics, then I actually get the 14 results. But why is this the case? isn't q=word supposed to search for word wherever it appears?
No, it's not. Your assumption that:
isn't q=word supposed to search for word wherever it appears?
is wrong. If you're using word as your only query, and nothing more - you're searching for word in the default search field. It does not search all available fields in all available documents.
Also be aware that the default query parser assumes that your query is in the Lucene Query Syntax. To handle more "natural" querying, you can use the edismax query parser. This query parser supports the qf parameter that tells Solr which fields to search, instead of having to use the cat:electronics syntax. Your example would then be q=electronics&qf=cat.
In the example documents you've given, qf=series_t author name cat is probably a decent value to search all these fields for the given query. You can also append ^<weight> to a field name to give hits in the different fields different weights. qf=name^10 cat would give a hit in name ten times the weight of a hit in the cat field.
I am creating a front end application which queries through a database using the Apache Solr engine, but I have two issues that I just cannot find the answer to.
When Solr is processing a Facet query, how do I get the facet to be a single phrase ("Department of the Navy (160)") instead of a broken up facet of 4 terms ("Department (160)" "of (200)" "the (200)" "Navy(160)").
Also, how do I remove certain facets from being queried, for example "and" "to" "the" etc.
Thank you.
Looks like your phrase is being indexed into a Text field which, among many things, splits by whitespace. This is very good for full text search but not for faceting.
You can have a duplicate field for this, of type string (and not Text), which is not splitted. You can still use the original field for searching but the new string field for faceting.
I want to do a phrase search in solr without analyzers being applied to it
eg - If I search for "DelhiDareDevil" (i.e - with inverted commas)it should search the exact text and not apply any analyzers or tokenizers on this field
However if i search for DelhiDareDevil it should use tokenizers and analyzers and split it to something like this delhi dare devil
any help would be appreciated
Not sure of any Out of the Box approach, you can copy field the content to a new field with no analysis.
And, You can define your own query parser and have the query being searched on the field with no analysis.
